This is Peyton reporting for our investigator, Goldilocks, who conducted a scientific experiment. Goldilocks had decided to investigate the types of chairs that bears sit in. To test this, Goldilocks decided that if she found a home of a couple bears, then she would be able to find at least two chairs and therefore would be able to test her experiment. She found a little house and walked into it. As soon as Goldilocks walked in the door of the house, she observed (something you can see, hear, taste, or smell) that there were three different types of chairs in the living room. Then Goldilocks made an inference that this was the house of three bears. An inference is what you can guess based on an observation. Goldilocks decided that the material of the chairs would be the independent variable, which is what was changed on purpose. There were three different types of chairs that Goldilocks defined as the levels of independent variable. The levels are metal, wood, and cushioned. These levels are the different types of independent variable. The part of the experiment that was measured is the dependent variable, which is the time used. The unit of measurement is minutes which is what Goldilocks used to measure the dependent variable. There are two constants in the experiment. Goldilocks made sure that the sizes of the chairs were the same and that the type of person testing the chairs stayed the same. Constants are things that do not change, so that the experiment is fair. After Goldilocks conducted this experiment, she restated that the purpose of her investigation was to determine the effect of the material of the chair on the amount of time the chair is used. Goldilocks (being the genius that she is) explained that a purpose is what you are testing in the experiment. By conducting her experiment, Goldilocks figured out if the type of chair affects how often bears use these chairs.
